Barite API

about this product

[BaSO4] A dense sulfate mineral that can occur in a variety of rocks, including limestone and sandstone, with a range of accessory minerals, such as quartz, chert, dolomite, calcite, siderite and metal sulfides. Barite is commonly used to add weight to drilling fluid. Barite is of significance to petro physicists because excess barite can require a correction factor in some well log measurements. Pure barium sulfate has a specific gravity of 4.50 g/cm3, but drilling-grade barite is expected to have a specific gravity of at least 4.20 g/cm3 to meet API specifications. Contaminants in barite, such as cement, siderite, pyrrhotite, gypsum and anhydrite.

Product Applications

Barite in Drilling Industry

Barite in Medical Industry

Barite in Plastic Industry

Description of the Product Applications

Drilling Industry:

 

The overwhelming majority of the barite that is mined is used by the petroleum industry as a weighting material in the formulation of drilling mud.  Barite increases the hydrostatic pressure of the drilling mud allowing it to compensate for high-pressure zones experienced during drilling.  The softness of the mineral also prevents it from damaging drilling tools during drilling and enables it to serve as a lubricant.  The American Petroleum Institute (API) has established specifications for the use of barite in drilling mud.

 

Medical Industry:

 

 An application where many people have heard of barite is within the medical field.  A high-purity form of barite is used in the gastrointestinal tract where its density prevents x-ray penetration, and thus is visible on an x-ray.  The outline of the gastrointestinal tract thus becomes visible allowing the determination of normal and abnormal anatomy.

 

Other Uses:

 

Barite is also used in a wide variety of other applications including plastics, clutch pads, rubber mud flaps, mold release compounds, radiation shielding, television and computer monitors, sound-deadening material in automobiles, traffic cones, brake linings, paint and golf balls.
